IMPROVEMENT IN PORTABLE OVENS.

Specification forming part of Letters Patent No. 189,403, dated April 10, 1877; application filed July 1, 1876.

To all whom it may concern:

Be it known that I, EDWARD BLOOMING- DALE VAN DE MARK, of the city, county, and State of New York, have invented a new and Improved Portable Oven, of which the following is a specification The object of this invention is to provide and construct a neat, cheap, and efiective portable oven, which may be heated by one or more distinct fires, and having the smoke-pipe extending from the upper fire pot or chamber down and around the oven, up to the point of lindrical pipe, B, whose sides are parallel, and

at the top ofv the said pipe I have a dumpgrate, O. The firepot D is bottomless, and is made c'one shaped, its lower end fitting snugly in the top of the pipe B, and is pro vided with a tight-fitting cover, E, so as to cause the smoke and heat, which wouldotherwise be lost, to run through the pipe F, downward and around the oven up to the point of exit at the rear.

This pipe F is to be made in sections at the bottom, so that it may be taken apart when necessary, to clear the same of ashes which may collect therein, the said pipe serving to retain the heat in the oven.

G G G are a series of movable shelves supported on rods H, which extend across the interior of oven. These rods are bent at one end, and fit into holes made and provided for them in the sides of the oven, and are set in the following manner: First, place the bent end in its hole, and run it in sufficiently to let the opposite end reach its hole; then slide the rod in until the bent end strikes the outer side of the inner wall, and all is secure, each shelf to have a broad flange, I, to keep the article being baked from burning.

J is an ash-pan, located under the oven immediately beneath the pipe B, so as to catch the ashes which fall through the grate O.

In some instances a very strong heat is necessary, and to provide for such cases I use a double fire, as shown in Fig. 2. In this case 1 reverse the cylindrical pipe B, and thus bring the dumpgrate O at the bottom, and, instead of using the bottomless fire-pot, I use a similarshaped fire-pot having a barred or perforated bottom, K, the said fire pot being provided with a bail or handle, L. so as to enable it to be removed with case when necessary. This second or upper fire-pot not only serves to heat the oven, but also affords a means whereby artioles may be cooked on top of the oven.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. In combination with the oven A, having coincident holes at top and bottom, the pipe B, the fire-pot, and the pipe F, extending from the latter around the oven, as shown and described, for the purpose specified.

2. The cone -shaped fire pot D, having a slotted or perforated bottom, K, the same being applied to the reversed end of the cylindrical pipe B, as shown in Fig.2, for the purpose of enabling two fires to be built within the oven, one in the fire-pot D, and one at the base of the pipe B, substantially as shown, and for the purpose specified.
